Sparffo,
Well said, I do almost 100% heavy industrial demolition, where we have large sites, vast amounts of slab and roadway, and with a good loader operator, the trails are clear of tire catching debris. But I Do agree with you on tight quarters, and rough demolition terrain, and can understand how in such areas how a track loader would be useful. I do see a lot of track loaders on tight big city jobs, but outside of the cities, they are pretty rare.
I also agree with your stance on thumbs, and grapples. a demo grapple is worth it's weight in gold, where as a thumb is more or less an after thought...unfortunately the company I work for now has 20 excavators, all of which have thumbs...no grapples, and no amount evidence can prove otherwise to the stubborn oldschool wreckers in charge.
